<h2 class="article-title">Faster Load Times For Any Framework</h2>
</a>
<h3 class="article-author">By Matthew Phillips</h3>
<p>
At <a href="https://www.bitovi.com/">Bitovi</a>, we’ve been working on utilizing HTTP streaming to speed up single-page application (SPA) load times for the last couple of years. We've developed a technique that accelerates page load times that we call <strong>incremental rendering</strong>, which went into DoneJS 3. Today we're happy to announce another project, Velocirender, which brings incremental rendering to any framework.
</p>
<p>
This article will:
<ul>
<li>Explain what incremental rendering is and how it improves page load times.</li>
<li>Explain how Velocirender makes it easy to get the benefits of incremental rendering with any framework.</li>
</ul>

| SSR | Client | Incremental |
|---|---|---|
| Pros | Pros | Pros |
| Full content (SEO) | Starts request assets sooner | Starts request asset sooner |
| Perceived perf | Easier deployment | Renders dynamic content sooner |
| Cons | Cons | Faster to interactive |
| Wait for DB reqs | No initial content | Cons |
| Delays until assets are downloaded | Latency delays UI | No SEO |
| Benefits more with H2 | ||
